function[snr]=radar_eq(pt, freq, g, sigma, b, nf, loss, range)% 代L的雷达方程%% Inputs:% pt == 峰值功率 in Watts% freq == 雷达中心频率 in Hz% g == 天线增益 in dB% sigma == 目标截面积 in meter squared% b == 带宽 in Hz% nf == 噪声系数 in dB% loss == 雷达损耗 in...
为什么要对 loss function 求偏导数? CW不要無聊的風格 “享”天地之美,析万物之理。 先概括性地回答问题: 为了让损失函数的值最快地变小,就需要沿着梯度的反方向走,因为梯度的方向是函数增值最快的方向。而计算梯度就需要求偏导数,偏导数是函数在某一轴上(比如题中的 分别构成2个轴)的方向导数,梯度就是由...

到这步为止,好像还差一个东西,那就是执行相应按钮所对应的功能,即按下“确认”键后,进到功能所在界面.使用的函数为Run_Function.所有的函数也都存在一个指向函数地址的二维数组 void (*FUN[5][5])()里面,要调用的时候只需传入对应的索引值即可. /*存放各个运行函数的数组*/ void (*FUN[5][5])...

最后就是常数c,这是⼀个超参数，⽤来权衡两个loss之间的关系，在原论⽂中，作者使⽤⼆分查找来确定c值。 下⾯总结⼀下CW攻击： CW是⼀个基于优化的攻击，主要调节的参数是c和k,看你⾃⼰的需要了。它的优点在于，可以调节置信度，⽣成的扰动⼩，可以破解很多的防御⽅法，缺点是，...
Second, to address the inadequacy of the CIoU aspect ratio of the original model loss function, we introduce a WIoU to enhance the capability of the boundary loss function. For the weak detection ability of the model, we embed a dynamic detection head (DyHead) to improve the detection ...
••Important•• Unless otherwise specified, the loss (negative log likelihood) printed during training is not a measure of the log likelihood; instead it's a "surrogate" loss function explained in the paper: differentiating this surrogate loss will give us an stochastic estimate of the ...
Then pass the signal, which should now have more intelligible CW tones present, through an active bandpass filter. You can try [this one here.] 3) Then, you should amplify the signal to adjust for previous filter loss and to set the level for adequate response at the LM567 decoder IC....
The cap shall then be removed from the test tube, and the tube, water and specimen shall be weighed to determine the water weight loss. If the water loss is more than 0.5 gram, the test shall be rerun. Otherwise, 5 ml of the test tube water shall be analyzed for fluoride ion ...
